Boeing has completed its $4.7 billion acquisition of Spirit AeroSystems, reabsorbing a critical supplier of airplane structures for commercial jets as well as defense aircraft such as the KC-46 and B-21. The acquisition allows Boeing to acquire all of Spirit’s Boeing-related operations, including fuselage construction for the 737 and other commercial jets that are the basis for military planes like the P-8A Poseidon maritime aircraft. As part of the deal, Spirit will function as a ’non-integrated’ subsidiary under Boeing’s existing defense unit, maintaining independent governance and operations. The move is expected to bring new opportunities to the Air Capital of the World, Wichita, Kansas, according to Sen. Jerry Moran.
